Answer:
a) ATP synthase is a molecular machine. This enzyme (protein) is in charge of
making ATP and is used by prokaryotes and eukaryotes. The fact that the same enzyme appears in both groups creates a relationship because the easiest way this could happen is by eukaryotes acquiring this mechanisms from prokaryotes. It is believed that in fact this happened through a process known as endosymbiosis, in which prokaryotic cells engulf other cells establishing a symbiotic relationship. After millions of years it eventually became 1 organism.
b) Since ATP synthase is a type of protein one could expect that the amino acid sequence that creates this enzyme should be similar between prokaryotes and eukaryotes and supporting the idea that eukaryotes evolved from prokaryotes.
Answer:
D
Explanation:
Let's assume there's two cuboidal cells, cell A and B
Cell A has a side of x
Let's find the surface area of cell A
SA = 6(L²)
SA = 6(x²)
SA = 6x²
Let's find the volume of cell A
V = L³
V = (x)³
V = x³
Cell B has a side of 2x
Now let's find the surface area of cell B
SA = 6(L²)
SA = 6(2x)²
SA = 24x²
Let's find the volume of cell B
V = (L)³
V = (2x)³
V = 8x³
As you can see, just by doubling the side length, the ratio between Surface Area and Volume went from 6/x to 3/x (the x² in the numerator and the x³ in the denominator cancel out forming 1/x)
The ratio decreased, therefore, D is the statement that makes sense
Answer:
D- The blackcaps will begin nesting at their wintering sites in Spain or the United Kingdom, resulting in a larger blackcap population migrating back to Germany after the breeding season has ended.
Explanation:
By the inhabitants of Spain and the United Kingdom placing feeders out for the blackcaps, the birds in their nesting sites during the winter will have food to eat, meaning a bigger population of the Blackcaps when they return to their main home in Germany.
This best predicts the effect on the blackcap population if humans in the United Kingdom continue to place food in feeders during the winter.
Answer: Kidney and lungs
When body pH become acidosis or alkalosis the first two organs that will be influenced is kidney and lungs. The body pH can alter your breathing frequency as carbon dioxide is making the pH more acidic. Acidic pH will make your breath faster so you can dump carbon dioxide faster. Acidic pH will also make your urine more acidic since the excess Hydrogen is dumped into the urine.
